Grand Theft Auto 5: How to find the hidden cave

This a a semi-easy tutorial on how to find the cave on gta5. It is on the side of the map near the quarry on the ocean front. It kinda digs into the mountains if you are zoomed in you can see it good. There is a boat and 2 jetskis there for taking and inside its kinda big and if you dive intro the water there is a weapon on the ground with armor vest.
